While coming back to work on the Peggy2 board and it’s interaction with my PSP, I needed to fix some issues with the IrDA to UART adapter (this is the piece that allows the PSP to communicate to Peggy2 through infrared).

Basically I had to create a new support for the IrDA transceiver and also to test if the bi-directional communication works (it does, like a charm…! ).
